Here's one faith group that fully supports marriage equality in Pennsylvania: PennLive letters

Unitarian Universalists have been celebrating same-gender commitment ceremonies for decades in our congregations. We have learned the spiritual benefits for all of us by publicly celebrating life-long commitment of love and support. Thousands of same gender couples are in strong, committed relationships that deserve our respect and support. When we afford gays and lesbians the same levels of respect that we give straight folks, our entire communities benefit magnificently.

As the values of inclusiveness, respect and equality increasingly are confirmed in courtrooms and churches across this country, we Unitarian Universalists lift our voices in support of the lawsuit recently brought by the ACLU on behalf of same sex couples who have been denied the rights to health care, life insurance, taxes, inheritance, and other benefits here in Pennsylvania.

We at the Unitarian Universalist Pennsylvania Legislative Advocacy Network believe that all citizens deserve the same civil rights and human dignity of marriage. We are committed to working to obtain those rights—whether through the ballot box, legislation or litigation.

The time is right. Polls show that a majority of Americans and Pennsylvanians now agree that gay and lesbian folks should not suffer as second-class citizens. And doing the right thing has material benefits as well. A recent Philadelphia Inquirer article pointed out that New York state has seen more than $200 million in spending tied to its 2012 ratification of marriage equality.
